That's called "refraction".
Type your answer here... it is called as the refraction.
Waves change direction as they enter or leave a lens due to refraction, which is the bending of light as it passes through a medium with a different optical density. This bending occurs because light waves travel at different speeds in different mediums, causing them to change direction at the interface.
Refraction is the bending of light waves when they pass through another substance. This phenomenon occurs due to a change in the speed of light as it travels from one medium to another, causing the light waves to change direction.
Refraction is the bending of light waves as they pass from one medium to another.
Sound can refract in different mediums due to changes in the speed of sound waves as they travel from one medium to another. When sound waves enter a new medium at an angle, they can change direction and bend, causing the sound to refract. This bending occurs because sound waves travel at different speeds in different mediums, which causes them to change direction as they move from one medium to another.
When waves change direction as they travel from one medium to another, it is called refraction. This bending of waves occurs due to a change in speed as the waves move from a medium with one density to a medium with a different density.
Refraction is the bending of waves as they pass from one medium to another of different density. This occurs because the speed of the wave changes depending on the density of the medium it is passing through.
Bending of waves, also known as refraction, occurs when a wave passes from one medium to another with a different speed or direction. This change in speed or direction causes the wave to change its path and bend. Refraction of waves is commonly observed in phenomena such as the bending of light in water or the bending of sound waves in the atmosphere.
The direction of electromagnetic waves can change when they enter a different medium due to effects like refraction, reflection, or absorption. These changes in direction depend on the properties of the new medium, such as its refractive index, leading to phenomena like bending, bouncing, or attenuation of the waves.

Refraction
As light waves enter water, they slow down due to the change in the medium's density. This change in speed causes the light waves to refract or change direction, bending towards the normal line. The extent of bending depends on the angle of incidence and the difference in the refractive indices of air and water.
